Wow, great visualization! Thanks for sharing the source.
A minor suggestion: For the first part of the demo i was thrown of by the fact that each second as laid out bottom->top. Maybe moving the time labels below the plot would provide a visual cue for the direction.
Yes, I agree with it being that way. I just think my brain parses the origin as being the corner that is closest to the "0" label. Therefore, if the labels where below the plot, there would be no parse error :)
